Boat-dived Trang pinnacle with coral tops and fishy gullies.
Hin Nok is a boat-accessed pinnacle between Koh Kradan and Koh Libong, with a compact loop of coral heads, gullies, and sand patches around a shallow summit. It is best treated as an easy scenic reef dive when the sea is settled, rather than a deep or technical profile, and the structure keeps the route interesting without much depth. Expect a lively Trang mix of angelfish, butterflyfish, bannerfish, parrotfish, barracuda, moray eels, nudibranchs, clownfish, pufferfish, and occasional turtles around the coral sections. Current can change from one side of the pinnacle to the other, so the calm-season window is the most forgiving.

Site Conditions
Safety Notes
Watch the exposed coral heads and stay oriented when the current changes around the pinnacle. This is a better dive with a guide and settled seas.
Access Restrictions
Boat access only; plan it as a guided day trip from the Koh Ngai and Trang islands area, and expect trips to be weather- and season-dependent.
Legal Notes
Follow local operator briefings and any marine-park or island access rules that apply to the Trang islands routing.
Community notes to help plan your visit.
Scuba Diving
A compact guided boat dive around a shallow pinnacle, coral heads, and gullies; easiest when seas are calm and the team can stay close to the structure.
Freediving
Not a primary freedive target; only the shallow top is usable in very calm conditions.
Snorkeling
Snorkeling is limited to the shallow summit and calm days; the main structure is better dived from below.
